Hi, Firstly-Sorry in advance for the length of this question! I've been playing with a mac intel imac OS X 10.4.7 and garageband just using line-in ports for electric guitar/inbuilt mic for acoustic guitar and vocals for a while now and I'd like to get it to sound a bit better using an audio interface... I'd also like to learn a bit of keyboard....or at least have a keyboard available for some song ideas for which I'd like to add bass lines & drums. I promise that I have researched until my heads spinning!! However, if one reads enough forum reviews and zzsounds customer reviews they directly contradict themselves (eg presonus firebox is great....oh wait..it's preamps are crap.....or line6 tonepro and gearbox software is great...oh hang on a minute its crap again!!...and its only USB!!)...I've just read another post saying that in the sub $300 price range that Im looking the difference in pre-amps isn't significant at all! Two weeks research down the drain!! AAAAArrrrggghhh! HELP!! (deep breath!) So....I know everything is subjective but, if I want to just have some fun and make my songs sound better quality than they do now and also play around with sound effects / drum samples / keyboard...maybe try out the "Logic Pro" software...is it worth considering an all in one like the Line-6 toneport KB37 for $300 (it has a 37key keyboard and Line-6 "Gearbox" software for guitar amp and vocal effects...but its only got USB connection): http://www.zzounds.com/productreview--LINTPKB37 OR..... The M-audio Ozonic is similar but FW connection but has some really dodgy reviews and for some reason isn't on sale at alot of places (being phased out perhaps?) http://www.zzounds.com/productreview--MDOOZONIC OR...is it better to buy a firewire audio interface (FW AIF) and a decent mic&cables and save up for a keyboard later? Come to think of it will I even need the Line-6 "gearbox" software (it has alot of guitar amp and vocal effects) if I have Logic Pro 7 or garageband?? Another main thing I'd like to do is save money on a guitar amp by only playing my guitar through whichever interface I choose and my computer. In this respect the Line-6 sounds fun (in principle)...but then again, if Logic Pro or Garageband can give me the same(or similar) amp/vocal effects then isn't the Line-6 box made redundant?...then it would seem better to just get a FW AIF and a keyboard later??? In that case my current choices for FW AIF would be: 1. Eco Audio Audiofire 4 (apparently its like presonus but with better pre-amps!) http://www.zzounds.com/productreview--ECHAUDIOFIRE4 2. Mackie Onyx Satellite (best pre amps for vocals but mixed reviews re-driver issues) http://www.zzounds.com/productreview--MACONYXSAT 3. Yamaha GO46 (not found any reviews but zzsounds gets 9/10 from 28 customers) http://www.zzounds.com/item--YAMGO46 4. I could also just get a tascam US122L ( or US144) as they are so much cheaper and come with a mic&cable bundle for $199 http://www.zzounds.com/item--TASUS122L My music is acoustic guitar&vocals which Im looking to expand with electric guitar/keyboard/drums on my computer....then maybe record a few disco/rock tracks! Any thoughts/recommendations/reality-checks welcome! Thanks so much to anyone who can help.
